UNITED STATES PATENT OFFICEc JOSHUA HUNT, OF `PROVIDENCE, RHODE ISLAND.

BLIND-STOP.

SPECIFICATION forming part of Letters Patent No. 275,492, dated April 10, 1883. Application filed January 6, 1883. (No model.)

To all whom it may concern:

Be it known that l, JOSHUA HUNT, of the city and county of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Fasteners for Window-Blind Slats; and I do hereby declare the following to be aspecication thereof, reference being had to the accompanying drawings.

Like letters indicate like parts.

Figure l is a front elevation of my invention. Fig. 2 is a vertical section. Fig. 3 is .a rear elevation of my invention,

My invention is a device for securing in position the slats of a window-blind; and it consists of a metallic tip adjustably fitted upon the rod and engaging with a bifurcated cramp, as hereinafter more fully specified.

In the drawings, Fig. 1 represents a windowblind,A, of the ordinary construction, having slats B and a rod, C, operating them, as usual. At the bottom of rod C is iitted a metallic clasp, D, having a vertical slot, a, in the' rear, the shape of which clasp isfully shown in the several figures. A tip, E, is cast in one piece with the clasp D, and extends downward in continuation of the rod C by the screw b pass- On the lower cross-piece of the blind A, Ivfasten by screws a metallic cramp, F, having jaws extending at a right angle with said cross-piece, between which jaws, at the inner end thereof',

there is formed a seat, c, which serves as av dead-lock for the tip E` when the slats are closed.

By means of this contrivance, as the blindslats are turned, the tip E, descending between the jaws of the cramp F, may be held therein at any desired position by slightly crowding the tip horizontally into the jaws, thereby causing a sufficient friction of the parts to hold them in place, which movement is allowed by the slight play of the staples d, which connect the slats and rod. The position of the parts when the slats are open is shown in dotted lines in Fig. 2.

To close the slats the tip is withdrawn from its friction between the jaws and lifted to the position indicated by the solid lines in Fig. 2. The extreme end of the tip then rests firmly on the seat c, and is locked in position by such engagement, and cannot be unlocked from the outside.

The utility of this invention consists, first, in its prevention of all rattling ofthe slats when closed, and which in blinds as heretofore coustructed is a great annoyance, especially in a windy night; secondly, it is a protection against the weather when the slats are thus closed and locked, excluding rain, snow, and wind; thirdly, it enables the securing of the slats in any desired position as ascreen against excessive sunlight and heat; and, fonrthly, it locks the slats against persons outside the house, thus concealing the occupants of a room from too inquisitive eavesdroppers.

The slotting at the rear of the clasp D enables me to adjust the device to any blind. In blinds as commonly constructed the rods which operate thel slats are made of various lengths; but the slot allows the clasp to move longi tudinally upon the rod, because the clasp clears the staples d by means of said slot.

I claim as a novel and useful invention and desire to secure by Letters Patent- 1. In a blind-slat fastener, the combination, with the rod C and bifurcated cramp F, of the adjustable clasp D, having'tip E, substantially as described. j

2. In a blind-Slat fastener, the bifurcated cramp F, having seat c, in combination with an adjustable fastening device attached to the slat-rod, substantially as described.

3. The improved fastener for slats of windowblinds herein described, consisting of the slotted clasp D, screw b, tip E, bifurcated cramp F, and seat c, applied to a windowblind, substantially as specified.

JOSHUA HUNT.
